abstract = "A hybrid RANS-BEM technique for the prediction of low Mach number flow induced noise produced by a body immersed in the flow is presented. Hydrodynamic data including turbulent kinetic energy and turbulent dissipation rate are obtained from a steady-state Reynolds Averaged Navier-Stokes
(RANS) simulation. Using a model of the turbulence cross spectrum, statistical noise sources are obtained and then combined with a boundary element method (BEM) model of the body to predict the far-field sound. The results from the hybrid RANS-BEM technique are presented for turbulent flow
past a wall mounted NACA0012 airfoil, with Reynolds number based on chord of $Re_{c}$=$1.1\times10^{6}$ and a Mach number of $M$=0.12 at zero angle of attack. The computed aerodynamic and acoustic
results are in good agreement with experimental results.",
